SCREEN-DOOR FASTENER.

Specification of Letters Patent.

Patented June *7, 1910.

Application led September 22, 1909. Serial No. 518,921.

To all 'whom it 'may concern:

Be it known that L'RUSSELL E. TUPPER, a citizen of the United States, residing at Sandwich, in the county of Barnstable and State of Massachusetts, have invented new and useful Improvements in Screen-Door Fasteners, of which the following is a speciication.

The invention relates to an improvement in checks and fastenings for doors, being particularly directed to a device designed particularly for use with screen doors and the like and adapted to check the closing action of the door and to secure the door in closed position.

The main object of the present invention is the provision of a check and door fastener, including a catch element to be secured to the door and a buffer element to be secured to the casing, the respective parts being so constructed as to retard the closing action of the door, during the riding contact of said parts, and finally interlock to provide a fastening means for securing the door in closed position.

The invention in its preferred form of details will be described in the following speciication, reference being had particularly to the accompanying drawings, in which Figure 1 is a broken perspective illustrating the application of the improved checking fastener. Fig. 2 is an elevation of the fastener with the parts thereof in separated relation.

Referring to the accompanying drawings, the improved fastening comprises a catch element 1 and a buffer element 2, the former being designed to be secured to the door` and the latter to the door frame or casing The catch clement includes a strip of approximately flat material which, at one end, is bent at right angles to the main length of the strip, as at 3, to provide an extension by which the catch member, through the medium of screws or other fastenings, may be secured to the door. The main length 4 of the strip projects at right angles from the section 3 and is terminally provided with a head 5 of approximately diamond shape in elevation. The head is of a width corresponding to the width of the strip, and is of somewhat greater length in alinement with the strip than in its transverse dimension. rlChe angularly related upper and lower edges 6 and 7 of the forward portion of the head are at a less angle to each other and to the longitudinal line of the head than the rear angularly related edges 8 and 9. By this const-ruction, the incline of the edges 6 and 7, from the forward point of the head, is less, or more gradual, than the incline of the rear edges 8 and 9, vfrom the rear end of the r head.

The buffer element 2 is shaped in approximate correspondelree with the shape of the head 5, but reversely arranged, that is the forward upper and lower edges l0 and 11 are at a greater incline with respect to the longitudinal median line than the rear upper and lower edges 12 and 18.

The Contact element is' secured to the door 14 so that the head projects in advance of the inner surface of the door, and the catch element is secured to the casing 15, through the medium of screws or other fastenings, so that its longitudinal median line is parallel with and slightly below the angular position of the longitudinal median line of the head 5. In other words, the forward point of the head 5 is, in the normal position of the parts, slightly above the rear point of the buffer element. The buffer is so spaced, with relation to the door length edge of the casing. that the head 5 will over-ride said buffer element when the door is in closed position, and in such closing it will be noted that the forward portion of the edge 7 of the head will engage and ride upon the rear upper edge 12 of the buffer element, the movement continuing' until the lowest point of the head, that is the juncture between the edges 7 and 9, will ride over the juncture between the upper edges 10 and 12 of the buffer element. Immediately succeeding this point, the rear lower edge 9 of the head rides upon and into contact with the forward edge 10 of the element, and as these edges have the identical angular inclination, they will contact particularly throughoutA their lengths and thereby secure the door against accidental opening.

It is understood, of course, that the main length 4 of the catch element is of spring type, and of sufficient strength to insure operative Contact of the head and buffer in the operation, it being noted that as the result of this arrangement the initial riding of the head upon the buffer element tends tov elevate the head, which is restricted by the tension of the main length 4 of the strip,`

with the effect of retarding or checking the closing action, said spring exerting sufficient tension, when the edges 9 and 10 of the head and buffer are in contact, .to prevent acc1 l dental separation of such parts and thereby maintain the door in closed position. The catch element is preferably of metallic structure, while the buffer element is preferably oi resilient or deadenng material, as rubber or the like, w'hereby the contact between the head and buffer is noiselessr, checking 'the ydoor without sound. .Both the catchV member :and the buffer are reversible, i so rthat wear `on any one portion, caused by continued use, may be remedied by reversing'f the parts. I acontemplate the use of any ma- #terial in constructing either fel'einent, pre-A ferring, however, the use of metal for thei catch element and rubber for the buffer element.

Claims.

l.. A door (cheek and a'stener including a L catch element and a buffer element, the catch velernent including .a 'spring strip adapted to be secured at one end to the door :and :a head a secured upon the strip and having its lower edge formed to provide two divergent angularly related surfaces, the buffer element having its upper edge formed with similar l surfaces, the respective surfaces of the edge .of each element being of different lengths and at different angles to the horizontal` 2. A door check and fastener including a catch element having spring connection with the door and a buifer element having fixed connection with the ldoor casing, lsaidfcatch element and buffer element each comprising :approximately :diamond :shaped bodies having their upper and lower edges presenting two divergent anguflarly related surfaces, the initial engaging Surfaces of fthe "elements beat .less inclination to lthe horizontal than the finally engaging surfaces of the elernents.
